  • The trial evaluated treatment responses in patients who were virologically suppressed, switching from a multi-tablet regimen to an investigational single-tablet regimen of Bictegravir 75 mg/Lenacapavir 50 mg. 
  • The efficacy of the pill was found to be statistically non-inferior to multi-tablet regimens.
  • The company is now further evaluating the combination in another late-stage trial.

Shares of Gilead Sciences, Inc. (GILD) jumped 2% on Thursday after the company announced positive results from a late-stage trial evaluating a combination of Bictegravir and Lenacapavir in adults with HIV.

The trial evaluated treatment responses in patients who were virologically suppressed while switching from a multi-tablet regimen to an investigational single-tablet regimen of Bictegravir 75 mg/Lenacapavir 50 mg (BIC/LEN).

What Did The Study Show?

The efficacy of the single tablet was found to be statistically non-inferior to multi-tablet regimens, the company said. Furthermore, the combination was generally well-tolerated, with no significant or new safety concerns identified.

The company now plans to submit the study's data to regulatory authorities.

According to Gilead, a single-tablet regimen could provide a new medication option with convenient dosing for people living with HIV by lowering pill burden. Participants in the late-stage study were taking between 2 and 11 pills per day for their HIV treatment, with about 40% taking their antiretrovirals more than once a day, the company noted.  

The company is now further evaluating the combination in another late-stage trial. The second trial is evaluating the safety and efficacy of switching from Gilead’s Biktarvy to a fixed-dose combination of Bictegravir 75 mg/Lenacapavir 50 mg in virologically suppressed people with HIV-1. Data from the trial is anticipated to be available before the end of the year.
